Idk if it's just me, but when I play PS3 on a 60hz tv, i DO notice some lag/refresh issues. Cousin has a 46 inch Samsung LCD, and when playing Black Ops i notice it the most.

I have a 42 inch Samsung LCD, but 120hz, and i like it much better. Played all kinds of PS3 games, including FPS extensively, like MW1, MW2, Black Ops, Medal Of Honor, and Battlefield 3, and never notice any issues.

When i get a new TV in my room, i'll probably go at least 46 inches and 240hz tho.

I'm almost definitely gonna get something with a refresh rate of at least 120/240Hz and a 5ms or less response time.

I don't trust the 60Hz LCDs for gaming...particularly fighting games. I'm a committed Tekken player and I had a bad experience with lag at a tournament so 60Hz/LCD is pretty much outta the question for gaming.
